Maxillary dental arch and occlusion in patients with unilateral cleft lip and palate treated with different delays in closure of the hard palate after early velar repair

Abstract

We wanted to find out if growth of the maxilla in 26 patients with unilateral cleft lip and palate (UCLP) was adversely affected by having the residual cleft of the hard palate repaired earlier than had been done previously in a 2-stage palatal closure protocol. The ages at repair of the hard palate of the present patients ranged from 38 to 89 months. Dental casts from ages about 3 years (before any repair of the hard palate), 5, 7, and 10 years of age were analysed. The results indicated that earlier repair of the cleft in the hard palate did not influence maxillary growth differently from the later repair.
